Internet Services API (ISAPI) has quickly become the standard for Internet service plug-ins. The exciting thing about this API is that ISAPI filters and applications can modify the functionality of a web or ftp server.
Our ~Home ISAPI filter gives the Win32 platform the same home directory access that the UNIX world has always enjoyed. This filter allows your web server to map a userid to its home (or some other) directory. This grants an NT machine the ability of accessing a users home page with an URL like: http://www.myserver.com/~smith
